Custom builds no longer work

[Roch Devost]

It is no longer possible to build a custom image with (or without) plugins since the command throws an error:

fatal: could not read Username for 'https://github.com': No such device or address
stat build.go: no such file or directory

This was using this very simple command:

docker build \
  -t rochdev/caddy-proxy \
  github.com/abiosoft/caddy-docker.git

Run docker rmi abiosoft/caddy:builder and try again.

That solved this issue. I am getting a different error now but only with custom plugins. I'll open a different issue for that if I can't figure it out.

Thanks!

The new error turned out to be because of #185
